Hi Roelof, that's awesome The best place to ask technical questions is probably the IRC channel where the Linux Mint and Cinnamon developers hang out; #linuxmint-dev on irc.spotchat.org. If you have patches to contribute, or find issues, you can submit these on GitHub: https://github.com/linuxmint. For other kinds of questions, probably best to contact Clem (you can find him on the IRC, or contact the development team by email: http://www.linuxmint.com/contactus.php). I'd be happy to try and get any questions you have, answered here also.

I have installed clutter which needed Gconf , so I installed version 3.2.6.Now I want to install ORBit2 and I get a message that Gconf-2 is missing.Do I need to re-install everything with Gconf version 2 or is Gconf-2 another package.

Yes, 1.6.7 remains the current stable release. The next stable release will be done together with the Linux Mint 15 release. Should be here in 1-2 months. You can follow news about Linux Mint on the main blog: http://blog.linuxmint.com/. A next release will be announced there. You can also follow the Cinnamon news page: http://cinnamon.linuxmint.com/?cat=1. The next stable Cinnamon release will also be announced there.

To get in contact with the developers the best way remains IRC #linuxmint-dev. Timezones/workschedules may complicate it a bit to get in contact with the right person.
